The WirelessHD specification is based on a 7 GHz channel in the 60 GHz
Extremely High Frequency radio band. It allows either lightly
compressed (proprietary wireless link-aware codec) or uncompressed digital transmission of high-definition video and audio and data signals, essentially making it equivalent of a wireless
HDMI. First-generation implementation achieves data rates from 4 Gbit/s, but the core technology allows theoretical data rates as high as 25 Gbit/s (compared to 10.2 Gbit/s for HDMI 1.3 and 21.6 Gbit/s for
DisplayPort 1.2), permitting WirelessHD to scale to higher resolutions, color depth, and range. The 1.1 version of the specification increases the maximum data rate to 28 Gbit/s, supports common 3D formats, 4K resolution,
WPAN data, low-power mode for portable devices, and HDCP 2.0 content protection. The 60 GHz band usually requires line of sight between
transmitter and
receiver, and the WirelessHD specification ameliorates this limitation through the use of
beam forming at the receiver and transmitter antennas to increase the signal's
effective radiated power, find the best path, and utilise wall reflections. The goal range for the first products will be in-room,
point-to-point, non
line-of-sight (NLOS) at up to 10 meters. The atmospheric
absorption of 60 GHz energy by oxygen molecules limits undesired propagation over long distances and helps control intersystem interference and long distance reception, which is a concern to video copyright owners. The WirelessHD specification has provisions for content encryption via
Digital Transmission Content Protection (DTCP) as well as provisions for network management. A standard remote control allows users to control the WirelessHD devices and choose which device will act as the source for the display. == Competition ==
